Postal Service To Honor Physicist Enrico Fermi On 100th Anniversary Of His Birth
The 34-cent Enrico Fermi postage stamp
WASHINGTON — Enrico Fermi, one of the preeminent physicists of the atomic age, will be honored by the U.S. Postal Service when a new commemorative postage stamp is issued at the University of Chicago on Sept. 29, 2001.

The first day ceremony will be held on campus at 9:30 a.m. in the Cloister Club inside historic Ida Noyes Hall, 1212 E. 59th St. The ceremony will be free and open to the public. The university will also be hosting a symposium that day in Fermi's honor.

"The Enrico Fermi stamp is a wonderful example of how commemorative stamps bring to the forefront the greatest achievers and achievements in American history," said Einar V. Dyhrkopp, member of the presidentially appointed Postal Service Board of Governors, who will dedicate the stamp.

The Enrico Fermi stamp commemorates the centenary of his birth on Sept. 29, 1901, in Rome, Italy. Fermi became a naturalized U.S. citizen on July 11, 1944.

Fermi received a Ph.D. in physics from the University of Pisa in 1922. From 1927 to 1938, he taught theoretical physics at the University of Rome. In 1934, while experimenting with neutron bombardment of uranium, Fermi — without realizing it at the time — became the first physicist to split the atom.

For his discovery of nuclear reactions brought about by slow neutrons, Fermi was awarded the Nobel Prize in Physics in 1938. After accepting the prize in Stockholm, Fermi immigrated to the U.S. with his wife, Laura — who was Jewish — and their two children, in order to escape anti-Semitic persecution in Italy.

In 1939 Fermi joined the faculty at Columbia University, where he taught physics and began conducting experiments with uranium in an attempt to create a controlled nuclear chain reaction. In January 1942 his work was transferred to the University of Chicago, where he supervised the design and assembly of the first nuclear reactor as part of the secret Manhattan Project (code name for the coordinated U.S. effort to produce the atomic bomb during World War II).

On Dec. 2, 1942, Fermi and his team made history when they achieved the first controlled and self-sustaining man-made nuclear chain reaction. Their success was fundamental to the production of plutonium and, thereafter, the actual construction of the atomic bomb became the primary focus of the Manhattan Project. In September 1944, Fermi moved to Los Alamos, N.M., to assist in directing the project's scientific team there. He was present when the first atomic bomb was tested in the desert near Alamogordo on July 16, 1945.

At the end of the war, Fermi accepted an invitation to teach physics at the University of Chicago's new Institute for Nuclear Studies. There he turned his attention to high-energy physics and helped develop the synchrocyclotron, which at the time was the largest particle accelerator, or atom smasher, in the world.

On Nov. 16, 1954, President Dwight Eisenhower and the Atomic Energy Commission gave Fermi an award for his "lifetime of accomplishments in physics and, in particular, for the development of atomic energy." He died of cancer on Nov. 28, 1954.

In 1955 the Institute for Nuclear Studies was renamed the Enrico Fermi Institute for Nuclear Studies in his memory. The name was shortened to the Enrico Fermi Institute in 1968. The Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill., was also named in Fermi's memory, as was the element fermium. The prestigious Enrico Fermi Award — the U.S. Government's oldest science and technology award — was established in 1956 as a memorial to the brilliant scientist.

Designed by Richard Sheaff of Scottsdale, Ariz., the stamp features a colorized black-and-white photograph of Fermi and a model of the carbon atom. The photograph was taken on March 26, 1948, when Fermi was a professor at the University of Chicago's Institute for Nuclear Studies. Graphite, a form of carbon, was used to slow down the neutrons in the first nuclear reactor.

To see the Enrico Fermi stamp, and other 2001 commemorative stamps, visit the Collector's Corner in the Postal Store at the Postal Service Web site at www.usps.com.

Current U.S. stamps, as well as a free comprehensive catalog, are available toll free by calling 1 800 STAMP-24. A selection of new stamps and other philatelic items are also available online at the Postal Store.
